(b) 22 employees were absent more than five days.

(c) 20 employees were absent from 6 up to 12 days.

Step-by-step explanation:

The data for the number of days absent during a calendar year by employees of a manufacturing company is given below.

(a)

The number of employees that were absent for fewer than six days is =

Frequency\  for\  class\ [0\ - \ 3]+Frequency\  for\  class\ [3\ - \ 6]\\=60 +31\\=91

Thus, there were 91 employees who were absent for fewer than six days.

(b)

The number of employees that were absent for more than 5 days is =

Frequency\  for\  class\ [6\ -\ 9]+Frequency\  for\  class\ [9\ -\12]+\\Frequency\ for\  class\ [12\ - \15]\\=14+6+2\\=22

Thus, there were 22 employees who were absent for more than 5 days.

(c)

The number of employees that were absent from 6 up to 12 days is =

Frequency\  for\  class\ [6\ -\ 9]+Frequency\  for\  class\ [9\ -\12]=14+6\\=20

Thus, there were 20 employees who were absent from 6 up to 12 days.
